Abstract

The effects of dietary supplementation of a commercial probiotic (Protexin) on daily feed consumption, egg yield, egg weight, food conversion ratio and humoral immune response in layer hens were investigated. In 7 replicates, a total of 280 40-week-old layers were given diets containing either 0, 250, 500 or 750 parts per million (ppm) for 90 d. 2. When compared with the controls, the food consumption, food conversion ratio and the proportions of damaged eggs were lower in the group consuming 500 ppm probiotic (P<0.05). 3. There was no significant difference between the controls and the groups receiving 250 and 750 ppm probiotic in food consumption, food conversion ratio and proportion of damaged eggs. Similarly, the egg yield, egg weight, specific gravity, and peripheral immune response showed no statistically significant differences between the groups.

摘要

研究了日粮添加市售益生菌（Protexin）对蛋鸡日采食量、产蛋量、蛋重、饲料转化率和体液免疫反应的影响。将280只40周龄的蛋鸡分为7个重复组，分别饲喂含0、250、500或750 ppm益生菌的日粮，持续90天。2. 与对照组相比，采食500 ppm益生菌组的采食量、饲料转化率和破损蛋比例较低（P<0.05）。3. 在采食量、饲料转化率和破损蛋比例方面，对照组与添加250 ppm和750 ppm益生菌的组之间无显著差异。同样，各组之间的产蛋量、蛋重、比重和外周免疫反应也无统计学显著差异。
